If I woulda-coulda ..
Hire a better NBA consulting President/GM than Mills/Perry.
Hire head-coach Jason Kidd or Casey 2 month after they loss their job.
Hire Fizdale to a 1 yr contract to Tank-Tank.
Resign Starter center DeAndre Jordan on July 1st, to mentor MitchRob, plus the KP trade wouldn't be looking so bad.
In the 2019 off-season hire one of the many unemployed NBA head-coaches along with Mike Miller to the Knicks coaching-staff, especially after having a 17 win season.
What to do NOW ???
Let Mike Miller be the interim head-coach the remainder of the season to improve the ball-movement in the half-court & transition offense, plus add some effort & speed getting back on defense plus add some help-defense on the wing, and boxing-out for the defensive-rebound.
